Final Project: Alternate Runs Data-set

Experimental design:  Switching every 4 trials in an alternating runs manner (no cues). Total of 8 experimental blocks were intended, but 60 subjects saw only 7 blocks. Across these blocks counterbalancing of four conditions: Both tasks unambiguous (1), both tasks ambiguous (4), shape ambiguous when irrelevant, color always ambiguous (2), shape always ambiguous, color unambiguous when irrelevant (2)

What the variables mean:

• block: 0 for practice, there are a total of 8 blocks per part and each block consists of 112 trials. So 896 trials per participant over all 7 blocks (not counting practice)

• bal: counterbalancing of conditions across blocks

• x, y, c2: irrelevant (already taken out)

• cycle: counting within full alternating cycle (8), switch at 1 and 5

• task: 1=shape, 2=color

• dimshape=specific shapes–4=neutral

• dimcolor=specific color–4=neutral

• correct: correct response (i.e., value of the currently relevant task dimension)

• error: 0 = no error, 1 = yes error

• response: actual response

• RT: or response time

#so this is telling us that our mean z-score for both control and switch is basically 0 (which is what we want to see) and that our z sd is 1 (which is also what we want to see). looking at the mean for RT in both switch and control, we see that the response time means tend to be a lot longer on average than the average response time for control trials (non-switch trials). this is so cool!

• What is the relationship between error and response time?

• What is the position of the cycle and the relationship from that to the response time?

• What are the dynamics of switching tasks? (5^th cycle or 1^st)

• Is there a difference in response time when people switch from task to another?

7. Pivoting

This code pivots the data so that each trial type has its own column (“switch” and “control”), and each column holds the reponse time trial.

<<<<<<< HEAD

alt_run_wide <- alt_run %>%
  pivot_wider(
    names_from = trial_type,          # Use trial_type as column names
    values_from = RT,      # Fill columns with response_time values
    names_prefix = "response_time_"   
  )

======= <<<<<<< Updated upstream

alt_run_wide <- alt_run %>%
  pivot_wider(
    names_from = trial_type,          # Use trial_type as column names
    values_from = RT,      # Fill columns with response_time values
    names_prefix = "response_time_"   
  )

=======

alt_run_wide <- alt_run %>%
  pivot_wider(
    names_from = trial_type,          # Use trial_type as column names
    values_from = response,      # Fill columns with response_time values
    names_prefix = "response_time_"   # Add a prefix to the new column names
  )

>>>>>>> Stashed changes >>>>>>> origin/main

Warning: Values from `RT` are not uniquely identified; output will contain list-cols.
• Use `values_fn = list` to suppress this warning.
• Use `values_fn = {summary_fun}` to summarise duplicates.
• Use the following dplyr code to identify duplicates.
  {data} |>
  dplyr::summarise(n = dplyr::n(), .by = c(id, bal, block, x, cond, trial, y,
  c2, cycle, task, dimshape, dimcolor, correct, error, response, trial_type))
